WATER-creeer TANK.

SPECIFICATION forming part of Letters PatentNO. 590,944, dated September 28, 1897'. v

Application filed February 19, 1896. Serial No. 579,932. (No moclell i To @ZZ whom t may concern:

Be it known that I, BEVERLY CnownLL,a citizen of the United States, and a resident of Asbury Park, in the county of Monmouth and State of New Jersey, have invented certain new and useful Improvements in Flush- Tank Water-Closets; and I do hereby declare the following to be a full, clear, and exact de-v scription of the invention, such as will enable others skilled in the 'art to'which it appertains to make and use the same, reference be# ing had to the accompanying drawings, which form a part of this specification.

My invention has relation to improvements in iiush-tank water-closets; and the object is to provide a Hush-tank that will be normally empty and which maybe operated to ill and flush the bowl when the closet is in use.

To these ends the novelty consists in the construction, combination, and arrangement of the same, as will be hereinaftermore fully described, and particularly pointed outin the claim. u

In the accompanying drawings the same reference-letters indicate the same parts of the invention. t

Figure l is a longitudinal partly-sectional view of my improved tan-k. Fig. 2 is an enlarged section of the siphon, with its float shown inelevation. y

A represents the Ordin ary rectangular opentop tank; B, theV service induction-pipe, provided with a self-closing valve I, having an eduction-pipe K opening near the bottom of the tank. p Y L represents a ball-iioat secured to the outer end of the lever Z, adjustably secured to the bifurcated arm u by the thumb-screw b and operated to open and close the valve VI as it is raised or lowered bythe water-level in the tank.

C represents the tanlcoutlet or flush-pipe,

, its upper end formed with a gooseneck N, the

shorter leg of which communicates with and supports a second pipe M, its lower end terminating within a short distance of the bottom of the tank, while its upper end is formed with a gooseneck N', the shorter leg of which terminates in an opening or valve-seat n,

adapted to be closed by the valve O, mounted on a valve-lever I), fulcrumed on a thumbscrew m, adjustably secured in an integral bracket m on the pipe M. The outerendof the valve-lever P is `provided with a thumbscrew r', which adj ustably secures the parallel arms oi the standard r to said lever, and the lowerend of said standard r carries a iioat R, which operates said lever and opens and closes the valve O.

E represents a horizontal lever fulcrumed in a bracket on one end of a diagonal crossbrace d, extending across the top of the tank, and the outer end of said lever is provided with the usual chain-pull e, while the inner end of said lever E is provided with a short chain II, the lower end of which is connected to the horizontal arm g of a bell-crank lever G, fulcrumed on a bolt t', secured to the lower end of the bracket F, depending from andsecured to the cross-brace d by the bolt D. An arm g on the lever Gextends underneath and across the path of the float-lever Z, and when the, chain e is pulled this arm g comesincontact with the iloatfleverland raises it audits float L. At the same time said arm g assumes a vertical position, as shown in Vdotted lines, so that the weight of the iioat-lever and iioat resting upon it will sustainit in this position until the level of the waterin the tank reaches the float and raises it from contact with. the upper end of said arm g,

g2 represents an integral depending arm on the bell-crank lever G, and it acts as a counterbalance, and it, with the arm g', is raised to an approximately horizontal position when the arm g is upright, and consequently the weight of the arms g g2 is all on one side and immediately restores the bell-crank lever c to its normal position when the .weight is re moved from its arm g. Y

The operation of the tank is as follows: The parts being in the position shown in full lines in Fig. 1, the tank is practicallyempty, the water having escaped into the flush-pipe O through the orifice S. 'When it is desired to flush the bowl, the chain e is pulled, which raises the bell-crank lever and iioat L to the position shown in the dotted lines, where it remains for the time being. In the meantime thevalve I is opened and the Water flows into the tank through the pipe K, and as it vrises it raises the iioat R and closes the valve O,

converting the pipes M C into a siphon, and at the same time that the level of the water in the tank has reached the top of the gooseneck N it has raised the float Il to release the arm g, which allows thc bell-crank lever to resume its normal position. The siphon action then discharges thc water through the outlet-pipe C, and the float L in falling closes the valve I, and as the water-level descends in the tank it lowers the Iioat R, operating the valve n, and allowing the air to iill the siphon, which permits the remaining water in the pipe C to flow noiselessly down through it to the bowl, and what water is left in the tank escapes through the orifice S, thus avoiding the objectionable gurgling sound which occurs in liushing with that class of tanks which are normally full of water when the closet is not in use.

Although I have specifically described the construction and relative arrangement of the several elements of my invention, I do not desire to be confined to the same, as such changes or modifications may be made as clearly fall within the scope of myinvention without departing from the spirit thereof.

Having th us fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, is-

A closet fi ush-tan k, comprising the valved inlet-pipe I3, the float-lever Z in operative connection with said valved inlet-pipe B and adapted to open said pipe upon the rising of the float, the bell-crank lever G, having an arm g, projecting into the path of said. Iioatlever Z, and an arm g@ the chain pull-lever E and the chain II connecting one end of said lever E to the arm g on the bell-crank lever Gr, in combination with an automatic iiushing apparatus, as and for the purpose set forth.

In testimony whereof I affix my signature in the presence of two witnesses.

BEVERLY cRowELL.
